Whether it’；s staying up too late watching Netflix， always browsing your phone， or just sitting for too long during the day， modern life can put a big pressure on our mental health and especially on our sleeping。 But fret not， science has you covered —； all you need to do is take your sleeping bag and your tent and head for the mountains or the woods。

“Our modern environment has really changed the timing of our internal clocks， but also the timing of when we sleep relative to our clock，” said Kenneth Wright， director of the sleep and chronobiology lab at the University of Colorado in Boulder。 “A weekend camping trip can reset the clock rapidly。”

An earlier study from Wright has already proven that our modern exposure to electrical lighting causes about a two-hour delay in our internal clocks， due to the fluctuations in the hormone melatonin。 Basically， we go to sleep later and this causes a lot of problems。 Back then， they showed that a week of camping in the summer sun shifts those clocks back and resets your body back to its healthy， natural rhythm。 But the first study took place during the study —； does the same thing happen during the winter？

In order to answer this， Wright asked nine active people to camp during the chilly Colorado winter， around the winter solstice， when days were at their shortest， while five stayed home as a control。 No flashlights， no phones， and no source of external light was allowed for the campers。 Results were even better than those for the summer study。
